“…The same holds true in regard to attempts at improving the correspondence of concepts with the clinical extension of the phenomenon, where Mojtabai's work [13] seems to be unique in showing how little inclusive our current classifi cations are. Ironically, while these shortcomings and the nosographic debate persist, there have nonetheless been a number of studies that seek clinical, epidemiological and biological data to help provide external validation for the syndromes [8,22,23] .…”

Delusional Misidentification Syndrome: Why Such Nosologic Challenge Remains Intractable

The delusional misidentification syndrome has lately been the object of lengthy psychopathological discussions. Controversies persist as to how best to define it, distinguish its subtypes and set their limits. Attempts to provide this syndrome with a better conceptual framework have usually relied on proposing new definitions and classifications. In this article, we suggest that some prevailing difficulties are basically related to two separate but intertwined issues: the self-reflexive property of the human mental functioning and the first-person linguistic expression of human experience. We argue that this discussion belongs to a broader context than the one it is usually referred to, as it deals with problems germane to conceptual psychopathological investigations in general. In that regard, DMS provides us with a very telling example, to the extent to which it has, at its core, to account for the puzzling phenomena of identity, which are particularly affected by cultural and linguistic variables.

ResumLes anomenades «síndromes rares» són aquelles que per la seua etiologia, casuística, símptomes peculiars o escassa prevalença poblacional, no solen ser abordades per la literatura científica. L'objectiu del present treball ha estat realitzar una revisió bibliogràfica i una anàlisi bibliomètrica de es publicacions científiques que des de de 1970 fins a l'actualitat s'han dut a terme en relació a quatre d'aquestes síndromes: síndrome de Capgras, síndrome de Cotard, síndrome de Münchausen i Folie à deux. A partir de la consulta dels bases de dades PsycoDOC, PsycINFO i SCOPUS es presenten els resultats obtinguts sobre les característiques clíniques, l'epidemiologia, el curs, la comorbiditat, l'etiologia i l'abordatge terapèutic de cada trastorn. Així mateix, s'analitza l'evolució al llarg d'aquest període de temps en el nom de publicacions, els autors i països més productius, les revistes científiques que han aportat un major nombre de publicacions i els aspectes sobre cadascun d'aquests quatre trastorns que han generat més interès en els investigadors.

“…These syndromes are important insofar as they have been shown to have a significant organic contribution [53,56] . Neuropsychiatric conditions associated with Capgras syndrome, for example, include Alzheimer's dementia [57][58][59][60] , Lewy body disease [61][62][63][64] , multi-infarct dementia [61,[65][66][67] , traumatic brain injury [68][69][70][71] , epilepsy [72] , cerebrovascular disease [73] , pituitary tumour [74,75] , multiple myeloma [76] , multiple sclerosis [77,78] , viral encephalitis [79] , and frontal lobe pathology [80] . It is estimated that between 25 and 40% of DMS cases occur in the context of an organic aetiology [56] .…”

The neural basis of psychosis is yet to be fully elucidated. In this review the contribution of schizophrenia-like psychosis of epilepsy, delusional misidentification syndromes and psychotic phenomena, such as auditory and visual hallucinations, to our understanding of the neural basis of psychosis is examined. Schizophrenia-like psychosis of epilepsy is associated with seizures originating from the limbic structures. Reduced seizure frequency, left-sided electrical foci, and neurodevelopmental lesions manifesting as cortical dysgenesis are known to influence the likelihood of developing schizophrenia-like psychosis of epilepsy. The delusional misidentification syndromes are a group of rare psychiatric symptoms in which impairments of face recognition memory are present. These conditions appear also to be associated with organic lesions affecting limbic structures and also involving both the frontal and parietal lobes. There is evidence that right-sided lesions predominate in the aetiology of delusional misidentification syndromes. Thus, the common link between schizophrenia, schizophrenia-like psychosis of epilepsy and delusional misidentification syndromes appears to be involvement of limbic structures in their pathophysiology. Discrete psychotic phenomena such as visual and auditory hallucinations appear to arise from functional changes in the same cortical areas subserving the normal physiological functions of vision and audition but also involving limbic structures. In conclusion, the limbic structures appear to be central to the psychopathology of psychosis but with involvement of frontal and parietal structures. These inquiries are revealing as much about psychosis as they are about the nature of normal brain function.
